Along the way, we’ll share our observations and insights, and as always, you can download the hard drive statistics data we use to create these reports. We’ll also check in on our 8 TB enterprise versus consumer hard drive comparison, and look at the storage density changes in our data centers over the past couple of years. In this update, we’ll review the Q3 2017 and lifetime hard drive failure rates for all our drive models in use at the end of Q3. In Q3 2017, Backblaze introduced both 10 TB and 12 TB hard drives into our data centers, we continued to retire 3 TB and 4 TB hard drives to increase storage density, and we added over 59 petabytes of data storage to bring our total storage capacity to 400 petabytes.
